“My short time at the Firm,” he wrote, “has shown me how much impact McKinsey can achieve in a short amount of time. I’m immensely proud of having played a very small part in that. However, creating impact is not an absolute good.” And doing good work, he added, doesn’t equate to doing good. “I believe it’s time for McKinsey to take precedent-setting action around client selection. As an organisation, McKinsey seems to talk a lot about values and principles without taking a valued or principled stand for much of anything.”
